BELT-FASTENER,

Specification of Letters Patent.

Patented July 13, 1915.

Application filed October 21, 1910. Serial No. 588,252.

My invention relates to fasteners for belts and the like.

My invention may be best understood by reference to the following description of an illustrative embodiment thereof shown in the accompanying drawing wherein:

Figure 1 is a plan viewshowing a strip of material incised to form a blank fastener; Fig.2 is a perspective view of the fastener separated from the strip and having its spurs bent ready for use; Fig. 3 is a section taken. on the dotted line 3-3, Fig. 2; and Fig. 4 is a plan view of the fastener applied to a belt.

The fastener herein shown as embodying my invention comprises a body 1 (see Fig. 1) having its opposite lateral edges incised obliquely thereto at' intervals in parallel lines of equal extent, thereby forming out of said body without removal of stock a plu rality of spurs 2 having shanks 3 and beveled points 4:. The lateral edges body constitute the beveled edges of said points While the opposite edges of the points are formed by said incisions and are continuations of one of the sides of the spurs. The opposed spurspreferably are not incised or formed directly opposite to each other, but may be offset or staggered to desired extent and herein are shown extending in opposite directions. v

A plurality ofblank fasteners such as just described may be conveniently incised without waste out of a continuous strip of metal or other material, and then said strip may be cut or scored and broken transversely or obliquely as on the dotted line (5-6 of Fig. 1 into blanks of suitable length to conform to the width of belt or other device to which the fastener is to be applied. 4

The fastener having been formed in blank the stock between the adjacent incisions and constituting the spurs 2, is then bent out of the plane of the body of the fastener, the op- 2 and '3), until they are in a posi- (see Figs.

5 of the tion approximately perpendicular to said body, but spreading or diverging somewhat as shown in Fig. 3 whereby to bring the medial lines of the opposed wedge-like points 4 parallel to each other and each of said lines perpendicular to the plane of the body 1. By bending the spurs into these posltions the points of the spurs, when forced into the adjacent ends of the belt or other material to be fastened together, (see Flg. 4) will be properly directed to pene' trate said belt perpendicularly to the face thereof. After the wedge edges of the points 4: have passed into the belt, the spreading shank portions 3 of the spurs will tend to draw the ends of the belt toward each other, thereby automatically always providing a maximum amount of belt material between the spur penetrations and the ends of the belt and reducing the liability of the spurs tearing out to a minimum.

. The fastener may be separated from the strip and the spurs bent in one operation if desired. It will be observed that when the described they are spaced, as well shown in a Fig. 2, their faces being parallel a d their edges, or the lines of their greatest cross sectional dimensions and strength, are presented substantially in line with the pull or strain to which they are subjected when the fastener is applied. By incising the spurs obliquely from the edges of the body of the fastener they meet said body obliquely to the axial lines of said'spurs and thereby are joined thereto with a greater amount of material and consequent greater strength with less liability to shear off or be separated from the body in use, than if said spurs were formed perpendicular to the edges of said body and also when bent present angular portions (3 serving not only as strong bases to connect the spurs to the body but also constitute solid extended backs to receive the blow or pressure when the fastener points are forced into the belt.

In use (see Fig. 4) the ends of the belt or other article are brought together, and the fastener placed centrally over the union thus formed and the spur points are then forced through as described and turned over or clenched on the reverse side of the belt in any suitable manner.

By my invention is provided a fastener which is simple in construction, readily applied, of great strength, is made Without Waste of stock and furnishes a permanent fastening for the ends united.

It will be understood that my invention is not limited to the particular embodiment tially perpendicular to the plane of said body. J

2. A belt fastener comprising a body, and series of spurs having substantially-parallel faces'and projecting from opposite sides of said body, the opposed spurs being bent toward each other, and the shanks of the spurs on one side diverging from the shanks of the spurs on the opposite side, each of said spurs having a point With a bevel and a straight edge and the medial line of each of said points being substantially PEPPER,

dicular to the plane of said body.

In testimony whereof, I have signed my name to this specification, in the presence of tWo subscribing Witnesses.
